It seems like a bug for test case//Re: A question about TestAdmin
failed.
It seems like that test case TestAdmin has some bug.
In version 0.90.2. Region can assigned to Region server by this code
// 5. Trigger immediate assignment of the regions in round-robin fashion
List<HServerInfo> servers = serverManager.getOnlineServersList();
try {
this.assignmentManager.assignUserRegions(Arrays.asList(newRegions), servers); // It waits for 10 minites.
} catch (InterruptedException ie) {
LOG.error("Caught " + ie + " during round-robin assignment");
throw new IOException(ie);
}
But In version 0.90.3. Region can't assigned to region server. (issue HBASE-3744)
// 5. Trigger immediate assignment of the regions in round-robin fashion
List<HServerInfo> servers = serverManager.getOnlineServersList();
this.assignmentManager.bulkAssignUserRegions(newRegions, servers, sync); // It doesn't wait for.
So function verifyRoundRobinDistribution can't get address and throws exceptions
List<HRegionInfo> regs = server2Regions.get(server);
public int hashCode() {
int result = address.hashCode(); // Region can't be assigned, So it seems like throw some exceptions.
result ^= stringValue.hashCode();
return result;
}

Jinchao:
Thanks for your hint.
I think the sleep call should be replaced with the following code which I
copied from HMaster:
MasterServices services = TEST_UTIL.getMiniHBaseCluster().getMaster();
AssignmentManager am = services.getAssignmentManager();
for (HRegionInfo regionInfo : regions.keySet()) {
try {
am.waitForAssignment(regionInfo);
} catch (InterruptedException e) {
LOG.info("Interrupted waiting for region to be assigned during " +
"create table call", e);
Thread.currentThread().interrupt();
return;
}
}
I tested the above change on Linux and it worked.
Please get 3744-addendum.patch from HBASE-3744.
Thanks

Thanks for your reply.
I know HBASE-3744. I had merged to my version.
Only run TestAdmin is also success.
But run all test case, it failed .
It seems like the configure of machine.
I try to sleep 60s before call verifyRoundRobinDistribution.

主题: Re: It seems like a bug for test case//Re: A question about TestAdmin failed.
HBASE-3744 introduced a change in how createTable() works.
By default, sync parameter is false:
public void createTable(HTableDescriptor desc, byte [][] splitKeys)
throws IOException {
createTable(desc, splitKeys, false);
}
because HBaseAdmin.createTableAsync() doesn't pass sync parameter to the master.
On a Linux machine, TestAdmin passed.
